I just bought two from the
http://www.dreamcottage.nu/english1/ website. Shipping was only $5.33. I bought them as unmounted and will mount them myself on the EZ Mount. They are $8.95 unmounted or $10.47 EZ Mount. For the two stamps, that's about $3 difference - and I have a LOT of EZ Mount stuff (that cost about $3 for 8 x 11 piece).
I'm excited to get these! They are different from any other stamp that I currently have (and I have a LOT).
